Kept me warm and comfortableI bought this for a trip to England and Scotland because and the weather forecast showed chilly temperatures during my stay. I wore this smart wool top for 7 days straight and it kept me warm and comfortable. Also it smelled fresh everyday. Wonderful base layer.

Excellent QualityI remember a lot of the old itchy wool long johns from childhood. This stuff is a lot more comfortable (and with the merino blend, not itchy at all).,,,,This is not the first pair of smartwool long johns that I've bought. I've got three pairs now, and the build quality is very good and seems to keep for years and years.

Keeps the smell awayI wear this long underwear all winter. It are amazingly warm. I ended up buying the bottom as well. The great thing about smartwool is that it does not hold oder at all. I can wear it over and over with little to no smell retained in the fabric. When I wear these out I will surely buy another pair.

Pretty niceI bought this shirt in the beginning of December to replace an old smartwool baselayer that i used for work (I'm a carpenter). it's a nice weight for everyday use with a sweatshirt over top. I'm 5'8 150lbs with a +4 ape index, this small fits nicely except the arms are too short.
